Hydroxyapatite Ball Implantation

At the time of eyeball removal, or after the eyeball was removed, the second-stage intra-cone cavity was filled with silicone balls. Treating diseases: eye diseases Indication At the time of eyeball removal, or after the eyeball was removed, the second-stage intra-cone cavity was filled with silicone balls. Preoperative preparation Regular preoperative preparation. Conjunctival sac culture and antibiotic susceptibility test, broad-spectrum antibiotic ophthalmology was instilled into the conjunctival sac. The conjunctival sac was washed with saline before surgery. Surgical procedure Hydroxyapatite filling 1. Cut the conjunctiva along the limbus, separate the subconjunctival tissue to the rectus muscle, and cut the optic nerve. Pressure to stop bleeding. 2. Cut the cornea, remove the eye content, and completely remove the pigmented membrane tissue. 5% iodine sputum burns the inner wall of the sclera and deiodine alcohol. The scleral shell was cut obliquely from the top to the bottom of the nose to make it into two hemispherical sclera shells. The pigment membrane tissue attached to the inner wall of the scleral shell is further removed. 3. Hydroxyapatite balls are implanted into the muscle cone cavity. 4. The two hemispherical sclera shells were resected intermittently or continuously sutured, and overlapped on the surface of the implant before and after, and were reinforced by a double sclera. 5. Layer suture the ocular fascia and the bulbar conjunctiva. Place a make up in the conjunctival sac. Eyeball ablation hydroxyapatite filling 1. Horizontally open the conjunctival sac posterior squamous conjunctiva, from the internal iliac crest to the iliac crest, sneak separation of the subconjunctival tissue to the inner, outer, and lower iliac crest, and take care to avoid damage and lift the diaphragm. The patient rotates the healthy eye to identify the position of the four rectus muscles. From the nose to the armpit, the eyeball fascia is obliquely cut from the upper to the lower part of the nose to form four tissue flaps, each of which contains a rectus muscle. . Expand the muscle cone cavity. 2. The preserved sclera was immersed in physiological saline for 10 minutes. Part of the scleral tissue around the original cornea was cut off and wrapped with hydroxyapatite balls. At this time, some of the hydroxyapatite balls were exposed to the outside of the preservation sclera. 3. Implant the implant that holds the sclera into the muscle cone cavity with the exposed side facing inwards. At the corresponding scleral site of the rectus muscle, a small window of 3 mm × 5 mm was cut out, and the four rectus muscles were sutured with the leading edge of the corresponding scleral small window. 4. Layer suture the ocular fascia and the bulbar conjunctiva. Place a make up in the conjunctival sac.
